Here is how you play the game: you walk with character A along path 1. At the end of path 1 you realize that you need character B here to advance. So you walk along path 1 with character B. Next you walk along path 2 with character C. Now, here you need character A. You walk path 1 backwards to reach the end of path 2. You walk back the paths with all three characters consecutively to follow path 3 to the exit... did this description bore you? Well, if so you know what it is like to play this game.
Besides this painfully boring repetitive walking around there is not much to say about this game. The story is OKish but nothing special (no great sense of humor or such). The puzzles are mostly fair, but (again) nothing special. The only positive thing about this game is that the artwork is really nice.
